Which engine light? I will assume you are referring to the Check Engine light. If so, it means the computer has detected a problem that is effecting the emissions controls. It can be a simple as a loose gas cap, or as serious as a clogged catalytic converter. Have the computer codes scanned and this will give you an idea of where to start. if you turn your ignition on off on off and on again and count the blinks it will blink pause than blink again ex(blink pause blink blink) would be fault code 12 and you can exces the codes meanings over internet or repair manual If you are OBD1 you can count the number of blinks and reference them by codes. If you're OBD2, there is a code reader you can rent (have someone with you to drive around to where you can read it when it throws a code -check engine could be on entire time and still throw codes-)then look code up; as previous answers stated, just didn't state with method was for what OBD. As first answer said, anything simple: fouled spark plug, ect.
